Note that beginning, fighting, and ruling have their own noun definitions, probably not only in Macmillan Dictionary. -- Also note that look forward to our meeting or look forward to the meeting is surely possible. -- And this is also possible: I'm looking forward to our seeing each other again.

@oerkelens, I' m not sure but in the sentence: "Seeing is good, doing is bad.", seeing and doing are not subjects and subjects are not nouns?

When they are truly used as nouns, they act like other nouns, indeed. But When they are used as verbs they are and behave differently.
